## Background
PRIORITY
The present invention claims priority under 35 USC section 119 and based upon a provisional application which was filed on Sep. 2, 2011 with a Ser. No. of 61/530,572


FIELD OF THE INVENTION
The present invention relates to the field of acoustics and more particularly to the fields of headphones and earbuds.
BACKGROUND
The distinction and advantages between headphones and earbuds has been repeatedly discussed by the users of each. Evidently, each one has its own strengths and weaknesses across a wide range of audio scenarios. Headphones may be good in a stationary, at home or in the studio environment. Headphone users typically may choose headphones for their better sound quality, noise-canceling capabilities and comfortable fit on the head/ears. Earbuds may come in handy when users are on-the-go, and need a quick and simple way of listening to audio that can be easily stored in their pocket or bag.
However, headphones and earbuds both have disadvantages of their own; headphones can be bulky, overly expensive, difficult to adjust to a perfect fit, and difficult to take on-the-go because of their larger size. Earbuds may be uncomfortable, fall out of the ears, produce less quality sound, and cause more hearing loss/damage. Earbuds may be easily damaged as they are wrapped around mp3 players, and stuffed in pockets and bags.
SUMMARY
The present invention includes headphones which may be adapted to detachably connect to earbuds.
A headphone and earbud device for receiving an audio signal may include a headphone including a speaker acoustic device to amplify the audio signal and to define a speaker chamber to cooperate with an aperture and an earbud to be detachably connected to the speaker chamber to transmit the audio signal to the speaker chamber.
The ear bud may be frictionally connected to the speaker chamber.
The earbud may include a earbud speaker to cooperate with the aperture.
The headphone may include an ear cushion member.
The speaker acoustic device may be a trumpet shaped device.
The speaker acoustic device may include a truncated cone shaped device.
The trumpet shaped device may include a neck which reverses in direction.
The truncated cone device may include a concave surface.
The truncated cone device may include a convex surface.
The speaker acoustic device may include a plurality of trumpet shaped devices.
The plurality of trumpet shaped devices may extend from a common base.
The headphone may include an earbud containing compartment for storing the earbuds.
The speaker acoustic device may include an amplification device.
The amplification device may be a microphone.
The headphone may include a first headphone and a second headphone.
The first headphone and the second headphone may be foldable.
The first headphone may be connected to the second headphone by a headband.
The headband may telescope from a first position to a second position in order to accommodate various users head size.

DETAILED DESCRIPTION
Today, there is a nearly equal demand for both headphones and earbuds. So by combining the two into one versatile product possessing the benefits of each, users will not have to choose between the two, or buy both separately.
With the present invention, versatile headphones of the present invention may be used as headphones or may be used with earbuds. The present invention may include of a pair of over-ear headphones, but with or without the built in speakers mounted inside the headphones. Instead, the audio may be supplied from earbud which may be detachably connected into an aperture on the outer side of each headphone. The aperture may be audio connected to a device that actively amplifies the acoustic audio from the earbud.
In one example, the earbud may be positioned at the base of a truncated cone shaped piece (kind of like a classic megaphone); this way the audio from the earbud may be enhanced and amplified as the audio enters the headphone, thus improving the users listening experience.
In another example, the headphone may include a miniature megaphone, microphone, or another electronic sound amplifier built into each headphone. When the earbud is connected to the headphone, the audio from the earbud may be amplified and enhanced electronically to make the headphones sound louder and clearer, thus making it closer to the experience of a pair of headphones without the earbuds.
For the non-electric audio amplifier cone the present invention may employ a speaker acoustic device as described below.
When the combination of earbuds and headphones are no longer desired, the user simply detaches the earbuds from the headphone, and then the user may have a pair of in-ear earbuds to use in the traditional way.
Also, the headphones may include a compartment that is capable of storing the earbuds when they are not being used with the headphones. The user would wrap the earbuds up, take off the headphone cushion/cover and place them inside the compartment of the headphone for safe keeping.
Advantages


    
    
        The present invention provides the comfort, quality sound, and noise-cancellation capabilities of headphones and the versatility of earbuds as desired by the user.
        The present invention provides only one pair of our versatile headphones, eliminating the need for 2 separate pairs of headphones and earbuds.
        Earbud sound quality is now enhanced into headphone quality audio
        If the headphone wires fray, the headphones may still be used with a new pair of earbuds providing working headphones and earbuds.
        The present invention eliminates the need to sloppily wrap your headphone wire around the headphones or an mp3 player. The compartment within the headphone provides storage for earbuds and wires. Also, this can extend the life of a pair of earbuds.
